Valladolid is a province of northwest Spain, in the central part of the autonomous community of Castile and León. It has a population of 529,159 people in a total of 225 municipalities, an area of 8,110 km2 and a population density of 65.24 people per km2.

The capital is the city of Valladolid. It is bordered by the provinces of Zamora, León, Palencia, Burgos, Segovia, Ávila, and Salamanca. It is, therefore, the only Spanish province surrounded only - and entirely - by other provinces of the same autonomous community. It's the only peninsular's province which doesn't have mountains.
